Backup Battery
The Messenger 570 system has an internal rechargeable battery that maintains full operation in the event of a power
outage. This battery must be enabled when the unit is put into service and disabled when taken out of service. All
information programmed into the Messenger 570 system will be retained whether or not the battery is connected to
the system.
NOTE: An auxiliary DC power output on the Messenger 570 system can be used to power external sensors and
accessories. It provides 12 volts DC (nominal) at up to 200 mA. This power is taken from the Messenger 570
system’s backup battery and will provide uninterruptible power, even during a power outage.
